Have a look at rtl/arm/arm.inc and look for the SwapEndian functions. If
you disable them by putting some bogus ifdef around them, then the
generic functions will be used. So far this should be the only place
which has the rev instructions.

In theory an ARMv5 binary should not crash (at least not because of
invalid instructions) on your android device.
